Browsers are essential tools for digital devices and are typically used daily. They provide access to information, communication, shopping, and entertainment. Many users stick with the pre-installed browser because it’s ready to use immediately. This is convenient but not always optimal. Differences are especially noticeable in privacy, features, device integration, and handling of new AI functions. Switching is usually straightforward and free.
Pre-installed Browsers and Their Ecosystems
Pre-installed browsers are considered technically advanced, secure, and well-integrated into their respective operating systems. “The pre-installed browsers are technically advanced, secure, and well-integrated, so users don’t need to worry about issues,” says Jörg Geiger from “Chip.” However, they are not ideal for every user.
“Pre-installed is also like an off-the-rack suit,” says Geiger. “It fits sometimes, but not everyone.” Many of these browsers are designed to bind users to their respective ecosystems and offer additional services through Apple, Microsoft, or Google accounts.
This is particularly evident with Microsoft Edge. “Edge on Windows stands out negatively because Microsoft tries quite aggressively to promote its own services to the user,” says Timo Brauer from the tech magazine “Inside-digital.de.”

Technology, Features, and Privacy Compared
Many browsers are technically based on the same foundation. “Many are based on Google’s Chromium engine—such as Edge, Opera, Vivaldi, or Brave,” explains Jo Bager from the IT magazine “c’t.” This ensures high speed and good compatibility with websites.
Firefox and Safari use their own engines and are considered full-fledged alternatives. Since Safari is only available on Apple devices, Firefox, according to Bager, is the only truly independent browser with its own platform.
Differences are evident in the range of features. While Chrome deliberately remains streamlined, Opera or Vivaldi offer extras like VPN services or integrated email functions. “The biggest differences for the user lie in the design and the features offered,” says Brauer.
There are significant differences in privacy. “The Chrome browser is widespread but lacks an ad blocker: Google, as the manufacturer and provider of Chrome, makes its money from data and advertising,” says Bager. Firefox, Brave, or DuckDuckGo, on the other hand, focus on integrated tracking protection.

Switching, Devices, and New AI Functions
Those who use multiple devices benefit from the synchronization of bookmarks, passwords, and tabs. This explains the popularity of cross-platform browsers like Chrome. At the same time, a lot of personal data ends up with the provider, which privacy-conscious users should consider.
Alternatively, bookmarks and passwords can be outsourced through independent services. For bookmarks, Bager mentions Raindrop.io or Start.me, and for passwords, Bitwarden or 1Password.
Switching browsers is easy. “When you download a new browser, you’re automatically asked if it should become the default at the first start,” explains Geiger. Switching is also easy on mobile devices, as app stores offer suitable versions.
AI functions are increasingly being integrated into browsers. “The topic of AI browsers is currently a major experimental field,” says Bager. However, he warns against careless handling of personal data. Brauer criticizes fixed AI integrations like in Edge: “Microsoft tries to impose its own AI assistant Copilot on the user.” There is consensus that AI functions should be able to be turned off.
